Thanks Marian,
I'll keep trying and if I get too frustrated, I'll just proceed with the game. The last ND game I played, Labyrinth of Lies, had serious bug in it that prevented me from finishing it. There was a telephone conversation that was supposed to take place that never happened. I even replayed the game 3 times, following the WT, in both Amateur and Senior levels and I could never get past that point. Disappointing!
